The venting method shown in FIG. 6 is known. In this method, first, a large roof to be constructed is laid separately for each block roof (hereinafter referred to as a block roof). Then
As shown in FIG. 4, the block roof 2 is laid on support members 4 such as columns separated from each other and a vent gantry 6 installed between the support members 4. Here, a jack 8 is arranged on the vent gantry 6, and a part of the block roof 2 is placed on the jack 8. In addition, the member of the code | symbol 10 connected with the center lower part of the block roof 2 is a bundle used at the time of cable tension.

The upward reaction of the upper jack 8 is performed to check the vent reaction force. Next, as shown in FIG. 6, a cable 12 is stretched between the lower end of the bundle 10 and both ends of the block roof 2 to perform a predetermined amount of the downward movement of the jack 8, and at the same time, a tension jack (not shown) or the like. Cable 12
We introduce tension into At this time, the operation of lowering the jack 8 is divided into a plurality of steps, and the operation of tensioning the cable 12 is also divided into a plurality of steps, and the jack 8 is gradually lowered so as to finally reach a predetermined design tension T S. The operation and the tensioning operation of the cable 12 are performed.
